Magnetic separation studies for a low grade siliceous iron ore sample
The investigations carried out on the low grade iron ore sample reveal the following conclusions. (1) The sample on average contains 43.8% Fe, 16.8% SiO 2 and 5.61% Al 2 O 3. (2) The mineralogical studies indicate that the major iron minerals are magnetite, hematite and goethite. And the gangue minerals are silicates and calcites.

Breakthrough In High Grade Rutile Beneficiation Method
About Rutile Ore. Rutile is one of the main minerals containing titanium. It is brittle, with a hardness of 6-6.5 and a density of 4.2-4.3g/cm3. Those rich in iron, niobium, and tantalum will increase in density, and the higher ones can reach more than 5.5g/cm3. It can be dissolved in hot phosphoric acid.
